------
 * Linux Kernel Networking by Rami Rosen

   more carefully explained it's still a good recomendation

* Linux Treiber entwickeln:
  It sure is a drawback that this is a german book.
  But it's quite recent, well structured and there are also
  other non-english (spanish) books/papers in this list.

Papers:
-------

  * On Submitting kernel Patches
    Contains 2 case studies of bigger patch sets and how (or how not)
    they were merged. I found it helpful

  * Tracing the Way of Data in a TCP Connection through the Linux Kernel
    Since this was written by me this inclusion may be a bit biased :p
    Neitherless I think this gives a good introduction on
    understanding/exploring linux internals using ftrace and an overview
    of Linux TCP internals.

The best is to highlight what really matters: the member name.

**Members**

Also, as the type is not part of LaTeX "item[]", LaTeX will split it into
multiple lines, if needed.

So, both LaTeX/PDF and HTML outputs will look good.

It should be noticed, however, that the way Sphinx LaTeX output handles
things like:

Moved the *duplicate C object description* warnings for function
declarations in the nitpicky mode. In nitpick mode, you can suppress
those warnings (e.g. ioctl) with::

  nitpicky = True
  nitpick_ignore = [
      ("c:func", "ioctl"),
  ]

See Sphinx documentation for the config values for ``nitpick`` and
``nitpick_ignore`` [1].

With this change all the ".. cpp:function:: int ioctl(..)" descriptions
(found in the media book) can be migrated to ".. c:function:: int
ioctl(..)", without getting any warnings. E.g.::

  .. cpp:function:: int ioctl( int fd, int request, struct cec_event *argp )

  .. c:function:: int ioctl( int fd, int request, struct cec_event *argp )

The main effect, is that we get those *CPP-types* back into Sphinx's C-
namespace and we need no longer to distinguish between c/cpp references,
when we refer a function like the ioctl.
